We report the fabrication of a novel easily available turn-on fluorescent water-soluble polymeric chemosensor for Hg(2+) ions that was simply prepared by micellar free radical polymerization of a water-insoluble organic rhodamine-based Hg(2+)-recognizing monomer (GR6GH), with hydrophilic monomers acrylamide (AM) and acrylic acid (AA). The chemical structure(More)
Two rhodamine derivatives, N-mono-maleic acid amide-N′-rhodamine B hydrazide (MRBH) and N-mono-succinic acid amide-N′-rhodamine 6G hydrazide (SR6GH), were synthesized by amidation with maleic anhydride (MAH), succinic anhydride (SAH) and rhodamine B hydrazide, rhodamine 6G hydrazide, which were identified by FTIR, 1H NMR and elemental analysis. Two(More)
An acrylic monomer bearing xanthene group, N-oxethyl acrylate-N′-rhodamine B hydrazide (ARBHE) was synthesized from N-hydroxyl ethyl-N′-rhodamine hydrazide (RBHE) and acryloyl chloride (Ac) in the presence of triethylamine in dry dichloromethane (CH2Cl2) at room temperature. The synthesized ARBHE was identified by FTIR, 1H NMR spectra and elementary(More)
2,4,6-Trinitrophenol (TNP, also called picric acid, PA) pose a large threat to environmental health, public safety and military security. Conjugated microporous polymers are emerging new fluorescence sensing materials for TNP. In this paper, we report the synthesis of two fluorescein containing conjugated microporous polymers (DTF and TTF) through the(More)
The novel water-soluble poly(vinyl alcohol) with pendant rhodamine B moiety as colorimetric and fluorescene chemosensor for Hg2+ ions was prepared by grafting poly(vinyl alcohol) using rhodamine B hydrazide and hexamethylenediisocyanate as fluorescent dye and coupling agent, respectively. Because of their good water-solubility, the polymers binding(More)
